Will the trackers work at the bottom of a quarry pit with no mobile signal?
Yes, but not as a continuous live feed. The store-and-forward log holds 300 entries by default while the unit is out of coverage and uploads retained records after connectivity returns. Longer offline periods can exceed available storage. The unit uses LTE-M with 2G fallback and has no satellite link, so on a site with no cellular service the records arrive only after the unit reconnects. Position availability and freshness depend on conditions, reporting cadence and network coverage.
